To determine the presence ofin an environment, a sample from the environment can be plated onto a growth medium that is selective for. The agar based growth medium can include a high concentration of crystal violet, in excess of 0.5 &#x3bc;g/ml. The process may be made further selective forby treating the sample with sodium dodecyl sulfate containing glycine hydrochloride for at least 4 minutes at room temperature, prior to plating.colonies will generally appear white while other colonies will generally appear stained purple or another color.

A combination toothbrush and toothpaste dispenser device includes a caddy that accepts tube of toothpaste and guides an integral toothpaste squeezer along a predetermined track. The squeezer is generally wedge-shaped and may be moved parallel and/or inwardly to the axis of the caddy. A modular and detachable toothbrush head mates with the caddy and includes a shaft with a central bore for delivering toothpaste to the toothbrush bristles. A refresh cup is further supplied to store and protect the combination device while not in use.

An active ingredient, such as particles of a pharmaceutical agent, is uniformly distributed within a transdermal vehicle, such as a gel or other viscous material. The method comprises filling said first container with a non-uniform mixture of a transdermal vehicle and said active ingredient, mounting the first container on a support member, and securing a second container to the first container. The first container has a restricted opening at its proximal end and a piston mounted movably within the first container for movement between a first position proximate said first container distal end to a position proximate said first container proximal end. The second container has a restricted opening at its proximal end and a piston mounted movably within the first container for movement from a first position proximate the second container distal end to a position proximate said second container proximal end. The first container restricted opening and said second container restricted openings are in open communication. The first container's piston is moved from its position proximate the distal end to a position proximate the proximal end and thereby forcing said mixture from the first container into said second container. The positions of the first and second container relative to said support member, are reversed and the process is repeated moving the mixture back and forth between the two containers until a uniform mixture is achieved.
